Recently we added Access Services to our SharePoint 2013 environment. After the initial setup we started testing the new implementation and stumbled over an error while accessing the details page of an app. This has nothing to do with access itself, more with apps in general.

After clicking on details you get an error message with the correlation id. So nothing easier to get the log regarding that error.

This leads us to a permission issue. We tried granting the App Management Service Account “SPDataAccess” permission on our logging database, which did not help.

As you can see in the log there is an user specified IUSR SID: S-1-5-17. This leads to a permission issue from IIS WebServer. Makes sense as all SharePoint Applications are running within the IIS and their Application Pools. As our App Management Service Account wasn’t the issue we granted our Application Pool Account under which the Web Applications are running, the “SPDataAccess” permission on our logging database.

Our scenario was that we wanted to upgrade our WSUS running on Windows Server 2012 to Windows Server 2012 R2 and changing the database to WID. The database wasn’t that important for us, as all computers placed in one group where all patches are approved. But we wanted to keep the content of 800 Gigabyte without redownloading all that stuff.

A huge advantage is if you have the data on a seperate drive or partition. Before you start, shutdown the WSUS Service and rename the WsusContent folder or move it to a different location.

Then you’re good to go. Reinstall or setup a new machine and install WSUS. During the initial configuration wizard its important that you choose “synchronize manually” and do not trigger a sync before or at the end of the wizard. Then copy the previous saved WsusContent folder to the location you’ve choosen in the wizard and replace everything. After that you can manually start your synchronization and WSUS is reindexing the whole content without downloading a huge amount of data. It should take around 3-4 hours, depending on your hardware and disk. You can see the status on synchronization tab.

After configuring LAGG (Failover) your NAS4Free instance is not reachable.

This can happen if you assigned an ip address to a network adapter (bce0, bce1, …) prior you switched to LAGG. You can simply fix this by opening /etc/rc.conf and removing all assinged ip addresses to single adapters.

I was trying to install NAS4Free (FreeBSD) on a HP ProLiant DL380G7. I entered Configuration Utility for the RAID Controller (HP Smart Array P410i) and removed all logical drives, as there is no need for a hardware raid if you’re going to use ZFS. I assumed no logical drives = JBOD but I was wrong.

The HP Smart Arry P410i does not support JBOD Configuration. HP seems to be aware of this so they created a…hmm… kind of a workaround. Simply boot up the latest smartstart package and start the smart storage configuration utility. In there you can create an array with RAID0, there is even a button for it.

After installing Windows Server 2012 R2 or Windows 8.1 you will be asked if this is a home/work network or not. Based on that windows will choose your network profile.

I was some kind distracted and accidently clicked in the middle of the desktop and the sidebar disappeared. Windows decided that this is a “No” and you will be on a public network. I’ve no idea why but you can not change it through the network and sharing center, all settings you’re trying to set will be set back to default of public networks. Like network discovery. So how to change it? Quite easy, just open the registry and navigate to the following path:

There will be at least one key in that list. Simply delete the one you want to reset and reboot your machine. After that you will be asked again. However I would only recommend that method if that happened to you right after the setup as I don’t know if some firewall rules will be reset or deleted.

I’ve tried to install some machines on my Hyper-V. All ISOs were placed on the second drive where data deduplication is enabled. With deduplication enabled I ran into the problem that no serial/license number was accepted neither the AVMA Key nor the generic KMS Key or my own key. After hours of searching for solutions on the web and no solution in sight. I copied the iso to drive D again. Suprise it was working! One day later I tried to install a new machine and it wasn’t working again. No key accepted. After moving it to drive C where no deduplication happens its working again.

I’ve rented a lot of linux vps around the world for testing and hosting teamspeak and other stuff. Not every application runs on linux so I decided to build a small home server with a low power consumption.

I stumbled over the list of components in the hardwareluxx forums and build my system based on that components. ( Link )

Here is my list:

Intel Pentium G3420

ASRock Z87E-ITX

Crucial Ballistix Sport Kit 8GB ( DDR3-1600, CL9-9-9-24 )

EKL Alpenföhn Silvretta

be quiet! Pure Power L8 300W ATX 2.4

SanDisk SSD 128GB

Kingston SSDNow mS200 SSD 30 GB

Cooler Master Elite 130

First of all I removed the Mini PCIe Wifi card from the mainboard as its not needed and plugged in the mSATA at the bottom of it. The small SSD can be used for the OS (Server 2012 R2) or as Host Cache for ESXi.
After putting all components together I enabled all bios settings allowing power savings and switched of the soundcard etc. I also tried to undervolt the CPU with the VCore Offset and got it down to -0,235mV.

Here are the results (power measurement):

ESXi 5.5 U1

Windows Server 2012 R2

Idle

18.2 Watts

11.1 Watts

Load

39.6 Watts

35.8 Watts

Make sure all drivers are installed and no usb devices are plugged in. The usb devices may prevent reaching a package c-state of more than 80.

The network drivers are a little tricky. For ESXi 5.5 followthis guide ESXi 6.0 includes drivers for Intel I217V and for Server 2012 follow this guide.
